According to New Mexico State Police Chief Pete Kassetas, authorities are in the process of executing three search warrants - one of the boy's school locker, one of his bag and a third at his family home.

"We got some preliminary information that possibly some of the students were warned by the individual, the suspect, prior to the shooting to not go to school," Kassetas said. "We have not corroborated that yet. I do not have a definitive answer as to if that happened or not."

The boy has not yet been charged with any crime and the investigation is ongoing,

ROSWELL >> Two students and a school staffer were injured after a 12-year-old boy opened fire Tuesday inside the Berrendo Middle School Gymnasium, according to New Mexico State Police.. The boy walked into the gymnasium carrying a bag at 8:11 a.m. on Tuesday morning with what is believed to be a shotgun.

Two students, a 12-year-old boy and a 13-year-old girl, were wounded in the incident and a school staff member received minor injuries. The boy was transported to the Texas Tech University Medical Center in Lubbock, Texas, and was listed in critical condition as of 2:30 p.m. The girl is in serious condition and undergoing surgery, according to police. The staff member received minor injuries but refused immediate treatment.

New Mexico State Police have not yet released the identities of the accused shooter and victims so authorities can first notify family members.

Gov. Susana Martinez said during a Tuesday afternoon press conference that an unidentified school staff member walked into the gym and asked the shooter to lay down the weapon, which he did, according to state police.

Shortly after, Berrendo Middle School Principal Susan Martin spotted Lt. Gary Smith of the New Mexico State Police outside of the gym, and rushed for assistance.

"She was able to get his attention, and they entered the school gymnasium where (Smith) was told there was an individual who was firing a weapon," said New Mexico State Police Chief Pete Kassetas.

Berrendo Middle School, located in northern Roswell, has around 600 students and its own security force, according to Roswell School District Superintendent Tom Burris.

"Your reaction is always shock. It's unbelievable that it could (happen)," Burris said. "We've done the active shooter training and the staff did an awesome job today. I can stand you and tell you that in the 10 seconds that transpired from the time of this thing starting until the teacher had control of the weapon, there was no cowardice. It was protection for our kids. Everyone acted and did their duties today."

New Mexico State Police are leading the investigation into the shooting at the middle school and are being assisted by the Chaves County Sheriff's Department, the Roswell Police Department and school officials.

Gov. Martinez is also helping to ensure all investigators involved have the necessary resources.

"Every resource we have available is going to be made available to the Sheriff's Department and state police," Martinez said. "This includes all investigative resources throughout the state."

Roswell Mayor Del Jurney asked for everyone's thoughts and prayers.

"I would ask that across the nation that people would pray for the city of Roswell and they pray for the victims and they pray for crimes like this that are occurring far too often in communities across this great nation."
